Submersible hydro turbine generators
are standard serially produced units. It
is a low head propeller design. Reaction
turbines require a much larger amount of
water flow than impulse styles, but can
operate with as little as two feet of
head, making them ideal for sites where
there may be relatively flat land, but a
large water flow. They use either a
'traditional' reaction style runner
(propeller runner).a specially designed
outlet tube increases the turbine power
output by creating suction as the water
exits the system.

In order to provide optimal performance
over a wide range, eight (8) different
fixed guide vane angles are available.
Runners are available with either four
(4) blades. The runner blade angles have
been set at the best degree. Induction
generator is designed for submersible
applications.

The turbine and generator are integrated
into a single unit ready to be lowered
down into simple compact structures. In
a hydro turbine generator all components
in the unit are designed to function
together from the beginning. There are
no transmission shafts to align when
installing. Draft tubes, seats are
prefabricated steel units, ready to be
cast into the structure. While running,
the generator is cooled by water flowing
around it.

The construction is simple and fast;
in most cases old structures can be
adapted for use with small changes. The
hydro turbine generator is not bolted
into the structure. It is simply lowered
down to a bottom seat for installation
and it can be easily hoisted up for
inspection and service. The
submersible concept dramatically
minimizes the impact on the environment,
especially on the landscape, because
most of the structure is placed either
in the waterway or underground. In some
applications the whole station is
hidden, by being placed below the water
surface. No more dominating power
houses. But don’t pull down old
beautiful mills or stations, put the
submersibles under them and use the
place in them as a museum or for other
activities.
